In English
It is good and helpful to have an enemy
Ignoring the unity of all mankind in the (divine soul), man relishes in quarrels and factions. He classifies some among his contemporaries as his friends and some as his foes. He manufactures duality where basically there is only unity. It is his own likes and dislikes, prejudices and passions that is reflected back, that creates all this reaction of love and hatred, all this resounding echo of factiousness and friction. Friendship and enmity arise from your heart; they are labels fixed by you, not marks which other people are born with. The same person is the thickest friend of one man and the mortal enemy of another - both because of his one act or one word!
